Application filed July 18,

T0 allwkom it may concern:

Be it known that I, JAMns G. ALLEN, a citizen of the United States ofA1nerica,residin at Detroit, in thefcounty of Wayne and Qtate ofMichigam'have invented certain new and useful Improvements in VVin- (lowScreens, of which the following is a v specification, reference beinghad therein to the accompanying drawings.

In my Patent No. 1,214,494, granted Feb. 6, 1917, there is disclosed awlndow screen having a collapsible or foldable frame which permits ofthe screen being rolled whereby the entire structure will occupy acomparatively small space when not 1n use.

This invention relates to a rigid window screen frame, incontradist'inction to the collapsible frame of. my prior patent, andthis invention aims to furnish such a frame;-with novel means fordetachably retaining it within the window frame, so that the screen maybe easily and quickly removed, particu larly during inclement weather orduring winter.

My invention further aims to provlde a window frame screen thatmay beadjusted similar to a sash and locked in a lowered or closed position.

The construction entering into my invention will be hereinafterdescribed and then claimed, and reference will now be had to thedrawings, wherein- Figure 1 is an elevation of the inner side of aportion of a window frame provided with a screen in accordance with thisinvention-.

Fig. 2 is a vertical cross sectional view taken on the line IIII of Fig.1;

Fig. 3 is a front elevation of a window screen;

Fig. 4 is a cross sectional view of the frame taken on the line IV-IV ofFig. 3;

Fig. 5 is an enlarged cross sectional view taken on the line V-V of Fig.1, and

Fig. 6 is an enlarged horizontal sectional view taken on the line VI-VIof Fig. 1;

In the drawing, there is shown a portion of a window having a sill 1,stiles 2, strips 3, and an upper sash 4 having a meeting'ra-il 5. Theupper sash 4 is slidable between the strips 3, in the usual manner, andthe lower sash has not been shown in order to more clearly show mywirescreen in the window 1921; seen no. 485,482..

lar frame havingside. rails 6 a top railr 'l' and a bottom rail 8, saidrailsha-ving the ends thereof suitably. joined to provide a rigid frameto which [maybe suitablyconnected the marginal ends of a wire screen 9.This wire screen may be of the usual interwoven wire fabric adapted toexclude flies,

and, other insects, and the edges ofthes'creen.

may be connected to .framefrails bybeads In some :in-

10 or other fastening means. I may be substituted 1 for the stancesglass screen 9.

The side rails 6 of tlie screen fr ame are provided with longitudinalrecesses 11 to receive sideflanges 12fof channelshaped re taimng members13, said reta ning members corresponding in length .to the frame rails6.

The retaining members ;13 may be shiftedon the rails 63 to increase-or[decr'easethe over-Q all width of the screen frame-andfholding theretaining members 13 normally eXtended are flat springs 14a'rrangedinthe upper and lower ends of the retaining members and connected to theframe rails 6, asjbest' 1 shown in Fig. '3.

To prevent the retaining members 13 from being completely shiifted offof the'rails 6 and at the same time afford convenient means ofretracting the retaining members 13, finger outward movement of thefinger pieces 15 and the retaining members connected there The loop orstop portions 1 6 of the 55 finger pieces 15 can be gripped when it isdesired to retract the retaining members 13 to remove one or both edgesof the Screen fromthe window frame, it 'is through the medium of theretractable retaining mem- 100.

pletely removed from the window frame- Q bers 13 that the wire screenmay be com Suitably attached to the opposed strips 3 of the stiles 2 arechannel guides 17 which extend from the sill 1 towards the top of thewindow frame and to a suiiicient height to permit of a wire screen beingraised relative to the sill 1. The retaining members 13 are adapted toslide in the channel guides 17 i and to facilitate moving the wirescreen the bottom rail 8 has a suitable handle 18,. i

handle 18 and the loop or stop portion 16 of the finger pieces 15' arewithin the screen frame and will not interfere with the operation of alower sash within the window frame; a

In order that the window screen may be locked in a lowered position, theretaining members 13, adjacent the lower ends thereof, have apertures 19adapted toengage studs 20 carried by the channel guides 17.

The retainingmembers 12 will'readily snap into engagement with the studs20 and said retaining members may be retracted when it is desired toadjust the window screen. Such locking means for the window screen maybe used at one or bothsides thereof and throughout the length of the,channel "guides 17 so that the window screen maybe of rubber, felt or aresilient material.

It is thought that the utility of the screen will be apparent withoutfurther description, and while in the drawing there is illustrated apreferred embodiment of my inventlon, 1t is to be understood that thestructural elements are susceptible of such changes as fall within thescope of the appended claims.

What I claim is l. The combination of a window frame, channel guidestherein a screen frame, channel'shaped retaining members slidablycarried by said screen frame and slidable in said channel guides, saidretaining members having openings adjacent the lower ends thereof,finger pieces attached to flanges of said retaining members adapted forshifting said retaining members to remove said screen frame from saidwindow frame, and studs carried by said channel guides and adapted toextend into the openings of said retaining members.

2. The combination set forth in claim 1, wherein said finger piecesinclude stops adapted toengage the inner edges of the screen frame andlimit the outer movement of the retaining members.

In testimony whereof I afiix my signature in'presenoe of two witnesses.
